Humane Society Silicon Valley will debut its new, state-of-the-art animal shelter in Milpitas at an all-day open house on Saturday.

The $25 million facility, funded through donations, will serve as a regional animal community center. It features a low-cost spay/neuter medical center, a community dog park and training center, doggy day care, boarding and grooming, a veterinary hospital with a public viewing room, an education center, a pet store and a pet-friendly cafe.

Christine Benninger, president of the Humane Society chapter, said the center’s many new features will help change the way people think about an animal shelter. No longer will it be a warehouse full of cages of unwanted pets, she said.

This new shelter features cageless animal habitats to simulate home environments and will be able to handle up to 10,000 animal adoptions a year.

Saturday’s open house will be held from 10 a.m. to 6 p.m. at 901 Ames Ave. near Milpitas Boulevard and Montague Expressway.

The event will feature a performance by Raggs, the singing canine from the Raggs Kids Club Band, as well as animal balloon making, coloring, a scavenger hunt, face painting and other arts and crafts for children. Tim Jeffreys from KUFX 98.5 (“KFOX”) is scheduled to be there from noon to 2 p.m.

And you’ll have a chance to make a video statement, pledging to help animals in your community in the shelter’s Community Room. Humane Society staff members will edit the video and post it on the society’s Web site and on YouTube.

Staff will also be available with information for those wishing to volunteer at the new shelter.

Animal adoptions, however, will continue to be done at the Humane Society’s shelter in Santa Clara for the next two to three weeks. That building has been sold.

Laura Fulda, Humane Society spokeswoman, said the new facility is California’s first regional animal community center and is one of the first environmentally certified “green” centers of its kind in the United States.

The center has an extensive on-site solar system that is expected to generate 40 percent of the facility’s energy needs from renewable sources, a kennel cleansing system that reduces water use while ensuring proper disinfecting, and artificial turf and native plants in the dog park areas intended to reduce the need for irrigation water.

Located on nearly five acres of land, the 48,000-square-foot center has homelike habitats for dogs, cats and rabbits.

As of February, Humane Society Silicon Valley had raised $20.4 million for the new center. It hopes to raise the rest soon. Donors can make payments on the shelter’s Web site at www.hssv.org or get more information at (408) 727-3383, ext. 878.
